This circuit is used to test triacs. It can be connected in series with a resistive load such as an incandescent light bulb. The circuit was suggested by Electronics Now magazine in November 1999.
We found this variable regulator circuit in a Radio Electronics issue from July 1984. It is one of...
The MC4741 consists of a quadruple 741. The power supply must be symmetrical, and the resistors must be...
Suggested by Sprague in the 1980s documentation, this circuit can control three-phase AC motors....
